Place the peaches in a lightly greased 9-by-13-inch baking dish. Layer the Marionberries over peaches. Sprinkle with the lemon juice and 1/4 cup of the flour. Combine remaining flour with the oats, brown sugar and spices. Cut the butter into flour mixture with a blender or 2 knives until crumbly and well-blended. Sprinkle topping mixture evenly over fruit and bake in preheated oven for 35 to 40 minutes or until crust is golden-brown and fruit is very hot and bubbly. Makes one 9-by-13-inch pan.
